'''A full-screen minute:second countdown timer.  Leave it in charge of your conference
lighting talks.

Once there is 5 minutes left, the timer goes red.  This limit is easily
adjustable by hacking the source code.

Press spacebar to start, stop and reset the timer.

Thanks for this script. Here is a patch to allow graceful exit when no (or more than one) argument is provided in the command line:

Thanks, very useful!

Thank you for great script :)

I was looking for something like this.

I needed some other functionality (countdown to exact time) so i forked this and add this function.

here is how it works:

Now it accept 0, 1 or 2 arguments (just ints)..

• if no argument is passed it start countdown with default 5 minutes (can be adjusted in code).
• if 1 argument is passed - than it countdown number of minutes you passed to it.
• you can pass 2 arguments - than it countdown to specific time - you have to pass hour and minute of target time...
  example: python .\countdown.py 9 15 this countdown to 9:15 - you have to use 24H format :)

Again thanks for script :)
